F80+ at Shamrock'n 5K: Ambrose Leads a Remarkable Field Across the Line

• Rebecca Ambrose, age 100, took the F80+ title in 38:51 — a 12:30/mi pace that left the field behind by more than three minutes.
• Kris B, age 102, is the oldest finisher in the group, completing the 5K in 58:42 at 18:54/mi to claim 3rd.
• The gap from 1st to 5th spans nearly 29 minutes — from Ambrose's 38:51 to Rita Goldberg's 1:07:38.
• Charlyn Frazier ran the tightest race to the winner, finishing 2nd in 42:07 — 3:16 back of Ambrose.

Let's get one thing straight before anything else: the F80+ group at this year's Shamrock'n 5K featured a 100-year-old and a 102-year-old finishing a 5K on a cool March morning in West Sacramento. That alone is the story of the day.

Rebecca Ambrose, age 100, was not just the winner — she was the dominant one. Her 38:51 finish at a 12:30/mi pace put her more than three minutes clear of Charlyn Frazier, who crossed in 42:07 at 13:34/mi. Frazier ran a solid, steady race for 2nd, but Ambrose was simply in a different gear from the gun.

Then there's Kris B. At 102 years old, she covered 3.1 miles in 58:42 — 18:54/mi — to finish 3rd. She is the oldest finisher in the group, and by any measure, one of the most remarkable athletes on the course today. Joan Coit-Gross, 81, was just 1:31 behind her in 4th, crossing in 1:00:13 at 19:23/mi, making that the closest battle of the day within the group.

Rita Goldberg, 83, rounded out the five-finisher field in 1:07:38 — a 21:46/mi pace over the full 5K. All five women finished. On a clear, cool morning with a light breeze, this group showed up, put in the work, and got it done in ways that most runners decades younger never will.
